I don't think anyone but the person shooting the bow can properly tune it. I mean, he can do some tricks and work some magic to enhance performance, but the shooter ultimately has to tune the bow. The difference in grip alone would cause differences, and ......you're a leftie. He's not.
And if the secret is fewer strands........ummm, that I would be skeptical of. Apparently it works, but at what cost? String durability? I don't know, just thinking outloud.
Don Take a look at the strings between the Drenalin and the new Drenalin LD. Thats how they were able to keep the same speed between those 2 bows. They just took out a few stands from the string and presto you have the same speed on a longer ATA bow and higher brace height. We have checked this at the shop I work. Actually sat down and counted them. and If memory serves me right the LD was about 2 strands less or so
