The only problem i have had with Long's, is under heavy brakeing with 3 fingers even with them adjusted all the way out,I can pull the leavers all the way to my knuckles.This has only happened on the track.
But its still something to concider .
Don't know about the short ones, still don't think I would change.
I have also installed long ones the Desmo. (Pazzo's)
I find that the pazzo's are a better than the other as Pazzo's are precision machined and have much tighter tolerances.
The others are injection casting which needs larger tolerance allowances for assembly, in my opinion the are a little loose in the assembly .
Although, the ASG are also machine just like Pazzo so same same .
They all have their own features so you need to make the choice for you .
But I like the Pazzo longs , only because i hold the bars right on the ends in the twisty stuff for extra purchase on the bars and need the extra length on the leavers
