The Quatro's are on the heavy side but IMO that's not such a bad thing! As for tinkering with them, you initially have to get them set up according to Mfr. specs. for them to function correctly. (just like any other high end mechanical type system) IMO the Quatro's are one of the safest set ups out there! The Strada's, RS-1's, E-Series are definately a close second when it comes to predictable release, but for ease of operation, they're the ticket! You can't go wrong with any of them.
