My only Hangup from doing dumbbell movements is that my current gym only has Dumbbells that go up to 110 lbs. our gym was renovated and before then we had heavy cast Dumbbells that went up to 130 lbs which was fine and what I used for flat pressing. Once the renovations were complete they got rid of the heavy cast Dumbbells and replaced them with rubber coated ones to protect their floor. Only problem is they only went to 110s...so now I'm doing some pretty high rep sets with them, and it would be nice to get some heavier ones
