I recently bought a 21’’ Hoyt Excel risers off the classifieds hear not because I needed it but because the price was good and if I didn’t like it I could sell it and get my money back. I have several sets of ILF limbs lying around so I started playing with different limbs. The limbs that shot the best was the Trad tech longbow limbs which make a 66’’ bow ,the only string that I had lying around was a Angel Dyneema endless loop. I tell you for a bunch of spare parts thrown together I’ll be hard press to find one of my other bows that shoots any better......stabow
