The Mercurytm is an entry level ball energized by the newly designed Orbitertm core. This high RG / low differential weight block delivers increased rev rate in the mid-lane along with smooth continuation down the lane.
Encapsulating this new power plant is the always successful Sure Grip IItm pearlized reactive coverstock. This mild reactive blend gives you fluid acceleration through the heads and dependable backend motion through the pins.
ROTO GRIPs "PRO PIN" technology is taking layouts and ball reaction to the extreme. Once only used on the Professional Tour for condition specific drillings, these balls are now being made available in limited quantities to the general bowling public.
Why? As the requests, requirements, and styles of today's bowler changes to address new lane conditions and patterns, STORM is answering by providing and packaging these items separately from the standard first run items due to their unique nature and value.
ROTO GRIP "PRO PIN" bowling balls are:
- All first quality ROTO GRIP bowling balls
- Manufactured with the same high quality standards as all other ROTO GRIP products
- Manufactured with the highest integrity
- Made with the same high quality materials as all other ROTO GRIP products
- Great for specialized layouts and drilling options
- Potential for enhancing dynamic use of core position
- Meet all A.B.C., U.S.B.C. and P.B.A. regulations
ROTO GRIP "PRO PIN" bowling balls are first quality bowling balls with pin distances over 5" from the center of gravity and top weight between 2 and 4 ounces. Through our testing, we have found that these balls lend themselves to a variety of drilling patterns outside the range of pins less than 5" which would require an extra hole to accomplish with standard pin and top weight specificiations. Based on the desired reaction, some Pro Pin drillings may require an extra hole for balance requirements.
Please visit your pro shop professional for assistance in determining the best layout for your style and lane conditions. If additional questions, please consult the "PRO PIN" Drilling instructions included in every box or call ROTO GRIP Technical Services at 1-800-369-4402 or email [email protected]

Since the breakthrough of fine tuning reaction characteristics by the use of mass bias placements in the 1990's, large pin out balls have been a staple for many ROTO GRIP Pro Staffers on the professional tours. Big pin outs occur when the weight block tips to one side of the ball. The further the weight block is tipped, the more the mass is biased to one side of the ball pulling the CG away from the pin. Advantages of these balls are as follows:
-Stronger preferred spin axis
-More drilling versatility
-Superior reaction charcteristics
-USED ALMOST EXCLUSIVELY ON THE PROFESSIONAL BOWLING TOUR....
-Enables drillers to use larger extra holes increasing flare potential and ball reaction
