As far as driving and spooling go, the off the shelf Nemans CVH RST cam (they only do one) is very very much like a Piper 285T2 it's lazy and so you lose at lot of low down to gain everything up top including spool up.
If I were to buy one again i'd ask them to make a copy of the 285T or the CVH33 these are much better cams IMO, unless you are just chasing BHP figures of course.
