I'm no expert, but I see stuff like the P90TM as a combination of many of the attributes of a P92 and a P28, taking aspects from both and creating a "combo" or "hybrid" of the two.
Sport chek actually has very good inventory online. And when they go on clearance due to being 2+ years old there's quite a decent selection for flex and curves. The most recent being the ft4 pro sticks. Was on sale for 199 since end of summer but recently went back to regular price and inventory is pretty much diminished.
