Mike,
My buddy Matt Bressler won the IBO National Triple Crown and took 3rd in the Worlds in MBR shooting an Allegiance..........nuff said.
If you have a shorter draw length like that and need the speed, don't handicap yourself further by lowering it further in the name of a strict target platform. You have to weigh the pros and the cons of each....will the Constitution be more inherently accurate? Maybe ,maybe not?
You have a shorter draw length and I think that would compliment the Allegiance just fine as evidence by the above example of Matt Bressler and I think his 28" draw length? (He was shooting his at 68# or so and 308fps)
I was given the advice of shoot the fastest possible bow that you canshoot accurately. If anyone tells you speed isn't an advantage, blah blah blah they're full of crap.
If I have 2 bows that I shoot basically the same accuracy wise and one is 20-30fps faster the choice is a no-brainer.
I shot my Constitution last year at 283fps and trust me there were times I wished that I had much more speed. Especially at Worlds......Itruly feel that if I had another 20fps on that bow I would have won. My yardage was pretty good but there were targetsout at the limit of the class range where they started dropping hard if you judged low and that was the difference on some very crucial X's.
All that said?........I shot my best score of the year a 322 IBO on a very long and tough 30 target course (as hard or harder than Worlds was) shot with my 60# Allegiance.
I think you might also be selling the speed a little short on a 27.5" Allegiance with fast mods and a nearly 300gr arrow. Keep the accessories light (loop and a simple Tru-Peep) and get rid of the silencers and eliminator buttons and I'd think you'll be into the low to mid 290's pretty easily?
The Allegiance is a very solid pointing bow, with a feel of being much longer that it really is........
I'll be honest with you........if you are shooting in the 260-270 range you are going to have a tough time competing with the big dogs unless you are superman with rangefinder vision.
I know the inherent advantages of neutral riser VS. reflex and long ATA vs. short but I will tell you flat out.....I'm a 30" draw length but if I was a millimeter under say a 29" draw length I would be shooting an Allegiance myself for 06' without a doubt.
One other thing......you might also want to consider either a target colored version with the Shrewd grip or a camo one and pick up a Shrewd and replace the factory wood one.
The grip is slim and comfortable but I know I have some hand placement issues with it due to the rounded profile. (Just a suggestion

)
