Cougs, all anyone is trying to say is think about your loyalties. For me, and just for me, if someone were giving me a new and expensive bow, I would not be singing the praises of another brand on a public forum. I may fall in love with another brand and go out and buy one, but out of loyalty to a person that has been so kind to me I would keep my feelings for brand X to myself. On the other hand, if I were giving someone a new and expensive bow, and then read on a public forum that they thought enough about another brand to sing its praises and were considering buying one, well I would have to think that maybe they don't really need my bow.
Look out for the interests of your benefactor. By doing so you will be looking out for your own best interests. Are you familiar with the expression, "Don't look a gift horse in the mouth"?
If you want a different brand for different technology then go buy it. Just keep it under your hat.
