I have Yakattack products all over my PA14 which my son now has. I have just purchased a PA12 and the Rail Blaza products looked interesting.
Save your money. I bought two of their items, first is the VHF holder, it's to small for the horizon VHF I own. Second is the u shaped holder, I use it for the boga, its fine for that.
I only found west marine that sold them here.
For rod holders stick with the local stuff. I like Scotty, or ram, both are more versatile to use and easy to get a hold of. Yak attack is also very good and again easy to get a hold of.
