babs: I do use a rest and plunger...makes tuning and shooting accurately (for me) much better.
The difference in the Winex and Border limbs has to do with performance. I rather like fast bows but not at the expense of being less accurate. The Winex limbs are carbon and foam constructions and are very quick, quiet and accurate. Sid at Border is big on speed and what he calls "torsional stability" which has to do with how much the limbs tourque when drawing and shooting. I find the Border limbs to be very fast and very stable. My groups at 20 yards with them seem to be tighter than with the Winex. Having said that, I would not hesitate to shoot Winex limbs again if I had to go down in weight again. I had heard so many good things about the Border limbs and the price was about the same I decided to give them a try. Glad I did. By the way, the Border limbs have a wood core. I was told by Sid at Border that the foam would not give me $100 worth of improvement. I am very pleased with my decision.
Up until about 2 years ago the only company in the US making ILF limbs was Hoyt. All the rest were from Europe, Korea, Japan and China. Now there are any number of US companies making the limbs so choices and competition is making limbs easier to come by but more confusing since the limbs come in various levels of performance. In general, the higher end limbs have minor differences between them but they outshine the lower price limbs in performance. Limbs from Korea are generally held in highest esteem for performance. It will be interesting to see what the future holds for the US bowyers. In other words, the ILF HUNTING bows are still evolving and since hunting in Europe and Asia is pretty much non existent the US market will, no doubt, determine the direction of ILF limb evolution.
