I'm also using 3M grip tape and plan to stipple as soon as I can find the time to practice and ensure I can produce a quality end product. In the interim, grip tape does the job, it's just not a permanent solution as it will have to be replaced when it gets worn down from use. If there is a possiblility of selling your weapons in the future, I would stick (no pun intended) to grip tape. If these are tools of your trade, stipple is a permenant solution.
