The Profit is Mint's third disc, and first putt + approach disc. While we don't want to call it the next Alpha, it's safe to say this is that putter that gets pretty close. It covers a plethora of shots, as a slighty overstable putter or easy to range driving disc.
Royal plastic is a "pro grade" plastic. The benefit to this plastic over Sublime, Apex or Eternal is the superior grip in all conditions. The tacky feel is uniquely soft yet firm. Royal plastic is also an ideal option if you want to it to wear in or "season" faster. Typically this type of plastic will get a straighter flight as it wear's in and loses it's high speed stability.
