Yeah, 260 is a good weight for a 6+ footer. What you can do if your gym schedule has to be erratic is just be instinctive, train one movement, and not follow a 'program' per se......like say you train on Monday, you can squat, do 5x5, then 2 or 3 sets of 8.....then say you can get to the gym until Thurs, you can bench and row....then next time you get to the gym, squat again, just to keep strength in big lifts and keep it stress-free.
