I just got a pair of Max 4 limbs from Bob this week. I am primarily a bowhunter and have had a 17" Gen I DAS riser from Dave's second run of risers. It is my go to riser. I also have a Dalaa riser of the same dimensions and length. The Max 4's I got are shorts and make a 58" bow...my favorite hunting bow length...not too short nor too long. Over the years I have shot Winex, XQ-1's, Hoyt and Border limbs. The Max 4's out shoot all of them. For the past two years I've had Max 2's and they are wonderful but the Max 4's have to be the best limbs I have ever shot. They are 46# @ 26" and give me 50# @ 28". I am shooting Axis 400 shafts, 200 grains up front footed at 29" length. Sting is a 10 strand 8190F endless that I make myself. Once I got the tiller at zero/even I put the setup (Dalaa riser) on my bow scale and got the 46# @ 26"...gave me 50# @ 28". The next step was to set the nocking point which I do with a bare shaft. No difference from the Max 2 limbs on the DAS riser, which are 54# @28". Then I determined what the best brace height was. The string I put on gave me a bh of 6.5". I shot that for a few ends and the bow seemed like it could be quieter so I raised it to 7" and finally found that 6.75" gave me the best feel (cream puff release) and the best bare shaft flight at 20 yards. Feathered arrows grouped better than I have done in many years and I haven't shot a bow since Nov. Speed (don't have a chrono) left all other bows I have shot in the dust. The limbs are absolutely stable and quiet. Zero hand shock which left me not wanting to quit shooting. The limbs are velvet smooth to draw and the release, as I have said, is cream puff. Just a joy to shoot and so easy to tune. All that remains is to shoot more so my form is more consistent and I think I may need to tweet my plunger a bit til I get the bare shafts shooting exactly like my fletched arrows. If hunting season was still on I would not hesitate to take the bow out in the woods right now. If you want to buy US and get the best limb around then you need to check out the Max 4's. Best limbs I have ever shot. I like them so much I am trying to figure a way to get a set for Laura who is shooting super short Max i's. Just so you know, I have shot Border Covert Hunters, actually shot J. Parnee's first CH at the Muzzy stump shoot, and i have to say, Bob's limbs are as good if not better than the CH's I have shot. Cannot honestly say anything about the Hex 7.5 limbs as I have not shot them, but for me, I think I have found the best limbs made in the US for my needs and shooting style. I have only had the limbs for a week so do not have pics. Haven't decided to keep them on the Dalaa or put them on the DAS...time will tell.
BTW, I turned 73 last Nov. and have had a bow in my hands since I was 8. I have shot many bows in my life, and although my statements above are very subjective, I believe that in time, in other people's hands who have the technology, my feelings will be substantiated.
