Papi: just keep in mind if you go with the Forge, def specify the 1M! They have a different version for the 1M which sadly is a bit more pricey than their N54 generic one, you want the former for no cutting/trimming, if you get the N54 'generic' you'll need to do some trimming. I'm heavily leaning towards Forge given the reviews and seeing its fabrication/craftsmanship, all others that require no cutting seem to scream a bit of Made in China to me... Let me know if it is something you wanna do soon, maybe we can bundle an order and get better pricing.
