Hate to be argumentative, but the amount of oil and the places it can be pushed by urethane on a house shot shouldn't do any more than force a boomer to go another board wider to get around the carrydown. Urethane is not going to make a house shot tougher, although it can make a flatter pattern ( like the Bear or high volume short patterns ) tougher. In my experience of sometimes throwing urethane on a house shot, the only person impacted by carrydown is me playing close to the oil line, not anyone throwing resin. High rev guys are blowing it up faster than I can carry it down. THS is all about carry. Anyone worth their salt should own the pocket with any ball in their bag. When I use urethane on a house shot it is all about being able to go a bit more direct to the pocket to help my carry.
Neither carrydown or blowing up the heads is usually much of an issue on a THS. It can be a much bigger factor on flat patterns where urethane can become a carrydown issue, and the boomers can blow up the heads in any area where us straighter guys want to play
