Fairly new to Compound bows, been shooting a PSE recurve for the last few weeks and at the range cant help but notice all of the advanced compound bows. Yesterday, I shooting next to a few Gents whom had Hoyt Alphas. Being an engineer by trade, I went home and did the research, to my understanding the split limb and parallel limb are two different technology (parallel being the improvement) ... but I cant find any info the specific improvement... possibly the parallel bows are shorter.. Any help is appreciated, I am afraid I got bitten by the bug and seriously thinking of getting one.. I kinda like the Maxxis/Alpha but their is a nice PSE BowMadness as well... luckily I have this forum and an old friend whom is heavily into Archery (though his technical information is in the recurves and with compound it's 5 or more years behind the time.. he was smart enough to tell me to make sure I know my draw lenght, etc before selecting a used bow as most if not all compound are custom fit to the shooter). Any information and advise is appreciated in advance..

Parallel vs Split are two different things - each with advantages.
Solid limbs vs Split limbs... The main advantages to split limbs seems to come from the ability to tune a bow for cam lean. Several different bows recently (mostly speed bows) have used different deflections (limb "weight") for the right and left limbs - thus helping to control cam lean. A split limb bow is typically "stronger" - because they don't have the "V" which makes solid limbs prone to failure. That would be the two main advantages that I can see.
Parrallel limbs are a fairly neat idea... When you shoot a bow the forces of the bow react thru the axles at 90 degrees to the limb. On conventional bows - the forces released at the shot tend to throw the bow forward. On a parallel limbed bow, these same forces cancel each other out - and thus you feel very little movement of the bow upon the shot release. So a parallel limbed bow will feel "quieter" when shot - and less movement is easier on accessories like sights and rests. Parallel limbed bows use longer risers and shorter limbs to keep the bow geometry correct (brace height and axle-to-axle). Shorter limbs are more "snappy" than longer limbs - and thus there is an inherent speed advantage to parallel limbed bows. The riser is one of the heaviest things on a bow - and making them longer costs a bit in overall bow weight. I am sure this has been one of the driving forces behind shorter ATA bows - it helps to compensate for the heavier riser. It also makes it cheaper to machine...
I think those are the main advantages... Maybe someone else will contribute some more.
Like in most posts, you guys go above and beyond the explanation of the question, including effects of design.. I REALLY Appreciate.. Thank you.. I got a long way to go
