I had the opportunity to weigh a variety of CB's and OB's during a recent visit to my local PH. I used a digital scale with quoted accuracy of 0.01 ounce.
For sets of OB's, I measured the 1B & 15B from each set to determine if the 1B is lighter than the 15B (due to wear).
Here are the results with photos of the balls in question:
Aramith "green logo" CB: 5.94 oz
Aramith "measles" CB: 5.84 oz
Aramith "red triangle" CB (from my late-90's SPA set): 5.89 oz
No Picture Available, Obsolete CB?
Black Lightning Bolt CB: 6.24 oz
Black Circle CB: 5.68 oz
Red Circle CB: 5.87 oz
Blue Circle CB: 5.91 oz <---newly added info
Red Dot CB: 6.72 oz
Super Pro Aramith OB's (late-90's set): 1B: 5.91 oz, 15B: 5.91 oz
Brunswick Centennial OB's: 1B: 5.91 oz, 15B: 5.92 oz <---newly added info
Cheap "no circle" OB's: 1B: 5.61 oz, 15B: 5.61 oz
Cheap "circled number" OB's: 1B: 5.87 oz, 15B: 5.97 oz
Cheap "big number" OB's: 1B: 5.92 oz, 15B: 5.95 oz (look similar to SPA's)
EDIT: Added Brunswick Centennial CB (blue circle) & OB's. I guess this removes all doubt that Sulac produces the Centennial OB's for Brunswick...they match the Aramiths in color & weight.
