Man this is such broad question. No mention on skill level, favorite type of terrain etc means internet suggestions may not be of much use.
I would say since you have been researching the NS Proto for years and you like the reported flex pattern just pull the trigger on that one. The NS group of guys make great products and you're supporting local Denver, CO business. The only downside of NS in my opinion is their graphics. I find them to be some of the worst in the industry but that is just my opinion. Others may really like them.
