I picked up a Protank 2 last night. Got it home, assembled, filled it up, and...I do not like that taste of that tip. Reminds me of drinking water from an aluminum thermos or something. It's my first metal drip tip and I guess I don't like them. It's like chewing on tinfoil. So, another trip to the store tonight to get some plastic drip tips. Anyone else not like metal drip tips for this same reason?
