yessir glynn, but understand ross wrote that years ago and he was also experimented with modifying trophy bonded solids due to the limitations of cast. he felt that the 475 was ideal back then.....it would be interesting to see why he felt the need to start moving from the ole cast and going to something else. i wonder why? don't know but i wonder? the 3 p's are the great debate and hopefully done in the good spirit of finding out what's the best.
