RE: Counterfit Little Extra; UPDATE
Well, I dont think the the HB .25 of old puts out anymore Power than the modern day Magnum XLS .15 I am not sure of the weight of the XLS, but I bet the HB is very close to it.
Now.. the K&B .21.....I KNOW will perform way beyond the XLS.. What a blast that would be. But it is heavier, It weighs the same as a Conquest .15
The wing area of the little extra is plenty for these hot applications...enough wing for the extra weight
