ILF limbs, within the limitations of the weight (your not going to get 70 lb. limbs, most likely) are highly devleoped and tested.
The limbs Morrison is recommending are extrmely smooth, very little that even appears as stacking, like going form 2 lb. per inch past 28 to 2.5 lb. They are extremely stable. They feel MUCH lighter than most limbs, and are pretty fast, maybe in the top 10%.
IMO, the tiller is nice but probably won't be needed by all that many people, and the adjustment range on the pull is good for tuning the bow to the arrow. Makes it easier to get perfect arrow flight.
I would guess that there is really a limited market for this riser/limb combintion, right now - as more people learn of the option, more demand. I just think that Morrison is just doing what he has been doing for years, working on a better mousetrap.We win. If he was just in it for the money, he can probably make all the bows he can with current designs. He found something that he thinks is probably a good thing.
Wait until he makes some of his longbow limbs in ILF fittings, and Black Swan starts making his available, and Adcock does and Border does.... What will happen then.
Great time to be shooting bows.
