I'm talking for both crosses and mains. I heard you need to use the staggered method with 4 clamps in order to ensure no slippage of mains, but I was wondering if 2xYonex is enough to hold 27-28lbs max. How bigg of a difference would the staggered method really make on those tensions when compared to just two yonexes?
I use 3. Hi Qua for for main, 1 yonex for cross. Yes 2 yonex should be ok for 28lbs. MBS are cheap you can get another pair. Hi Qua are only good for main get the smaller version if you want to use for both main and cross https://www.mybadmintonstore.com/shop/product_info.php?cPath=25_62_153&products_id=1144 https://www.mybadmintonstore.com/shop/product_info.php?cPath=25_62_153&products_id=523
I use a drop weight with 2 yonex flying clamps. The flying clamps are great. The clamp on the tensioning mechanism slips sometimes on high tension and slippery strings, but the yonex clamps have never had that problem for me.
Two Yonex's flying clamps are enough, but I always use a Delrin flying double clamp (the photo below) made for tennis as a starting clamp, when I double-pull the first two mains. Why ? Because I had some issue in the past when using other clamps made of steel as a starting clamp in the very beginning of the stringing process (starting the mains). The delrin double clamp with the blocking system has 2 advantages : less risk of slippage (you can adjust the force of the clamping system) and if it slips, it doesn't damage the string.
