Idk if this will help you or not, but fwiw, I picked up a Dakine Pipe bag on sale and couldn't pass up the price. It is a 145cm in size, but my 146 fits just fine. I kind of have to push the tips in at first, but once it's in there, the size is fine. Taking it out is the same; I have to pull the ends off a tip but it's not a big deal.
If you want to carry other items in the bag, you might want more room. To give you an idea, I carry my mitts and a towel in mine with plenty of room to spare. I could fit my helmet in there as well (between the bindings), but prefer not having the helmet bang around unnecessarily. My pants would also fit, now that I think of it (but the less grime on them, the better imo).
