Hello all. As PV user (and advocate) for several years - I have a few "for whatever its worth" comments about some things that I have learned the hard way and might make life easier for anyone just exploring PV:
1. Molding the back plate makes for a much more comfortable and supportive, (and stylish) fit. Oven at 250, monitor closely, gets very soft very quickly (walk away and you'll wish you hadn't) ... put back in vest and wrap with 6 inch ace til cools.
2. I found deep water ups a real problem at first - Until focused on a couple things - up accompanied by a lot of load on straps, body, boat, and infact kept breaking the back plate. (If that happens, finally found a way to fix and reinforce the plate). Thing that made ups easy for me with PV: make sure straps are long enough to get hands and handle in front of knees as soon as line loads from the boat, use a very firm "up" / acceleration from the boat, and most important - let rear foot heel immediately collapse (fully flexed knee) against rear foot buttock; then ski planes off immediately and all problems and high drag loads go away:)
3. Drag of strap through vest apparatus is the biggest "operational downside" to the vest. This can be greatly diminished by replacing the gizmo that comes with the vest with two small eye bolts with straps through the eyes on the back of the plate, and nut and bolt cut short and padded on the inside. It's also possible to find slipperier straps at hardware store. Also helps to put some packing tape on the margin/edge of the back plate along the axis of the straps to decrease sliding friction and reduce abrasive wear on straps.
4. Strap length: Straps that are too short are dangerous. This has worked for me: with arms at side, extend the wrist and adjust straps til this position just engages tension in the straps - then small adjustments from there. Another check: adjust such that when in "full lean", (try on dry land) straps are tensioned with elbows just a touch shy of full extension - this will allow full stack and really unload unhappy upper extremity joints, and pass load thru the plate to hips.
5. Consider a snap shackle on non dominant end of strap - then can "clip in" to the glove D ring at last moment and unclip at end of set or after crash - much easier in and out of boat, swimming, looking less geeky. The D ring on the glove will rotate 90 degrees - no downside there. By keeping the opening on the snap shackle towards wrist/ forearm - I can't see any way for the rope, handle, or anything else getting tangled in a crash. I have used this for three years .. no issues.
6. With clincher gloves, I do think there is some risk of little finger hanging at junction of handle and rope with conventional handle. I have used radius handle and no problem. Consider sewing or taping glove tip of little finger to the ring finger. Absolutely no downside and will protect little finger. I have not tried without the dowels in the glove, but it seems to me that discarding dowels would remove a lot of the "mechanical advantage" of the whole set up. (But maybe I will try it - as others recommend)
6. I never use the arm bands. Individual user has to decide if that's safe. Never had any incident that even considered "close call". I do ski with shorty. The metal fastener that secures the straps at desired lengths can scratch on wet suit on ups - duck tape prevents.
7. I don't think PV will make anyone ski better, but just a lot longer, while protecting a lot of the things that get wacked as we ski.
8. I have some pics, but still can't quite figure how to post:)
9. Sorry long post. I hope some part of this helps someone exploring PV.
