thought the a1 a2 and the web 110 were about the same?

 

yes and no.. the duration is longer but the lift is shorter.. I really like them.
Mister HP said mine have more 5000 rpm power but the 109/110 are better uneder 5000
I have the piston so it compensates and I have no low end issues, Other then traction, it likes to rip!
o n d u n e s . c o m has the specs on the a1a2. I know hightower has them also.

 

i had them in the stage 2 , they worked good i just liked the 109 better but that was in the 720 also they might suck in a stage 2
