Like a friend says; "The common BLAU steel caps are PIGS, when compared to the All-Aluminum racing version of the same BLAU cap". Here is the proof...

Here is the 'dime-a-dozen' heavy-weight all-steel BLAU cap weighing in at 345 grams https://pbase.com/9146gt/image/164745714.

And here is the ALL-Aluminum racing version at only 188 grams https://pbase.com/9146gt/image/164745419 including the FIN which the steel cap does not have. Add the fin to the steel cap and the weight difference is even more pronounced.

I suppose he's right, the 'steel version of the BLAU caps are PIGS!'
