Once again Lance, you outdid yourself.

Just wonderful pieces of equipment.

The 67s in the Holy Grail collection are all L71. L89s had the same HP rating as L71, at 435, on account the heads did not contribute any more HP, only a weight savings, plus the option was expensive, and when offered one or two L89s back in the day I passed. Did have 67 & 69 L88s but didn't like them much and subsequently didn't keep them long. Never claimed to be smart.
