I've used FS Discount arrows from time to time. I've never had a problem with any of my orders from them.
As for using sponsors on here, that's fine with me too since I've bought from Braveheart Archery many times. But, sometimes that's not feasible. As an example, "no" sponsor here on Trad Gang carries the Eclipse X7 2212 full length aluminum shafts and 2212 RPS inserts, which I build into arrows, so that forces me to get them from Bowhunters Superstore in Wellsville, Pennsylvania. This company has been supplying me my hard to find aluminum shaft sizes not normally used by bowhunters, for the last 30 or more years. The reason I shoot a 2212 is because Easton discontinued the 2113 shaft size I had used for many years so that forced me to adapt and I was lucky to find the 2212 size was a very good replacement.
In essence, when I buy my trad archery stuff, I spread the wealth around depending on who has what when I need or want it.
