I think I know what Saikat means.
Perhaps he can correct me if I'm wrong, he may have a lot more experience than I have with this type of equipment.
I have a very similar set up...a Hots 77XH and an SW18000. I think the feeling that the reel outpowers the rod comes from the fact that these rods are light and don't look substantial enough to be able to withstand 100lb line (in fact having held both the Hot's is even lighter than the Atlas). Not so long ago a rod the dimensions of my Hot's would have been a 30-40lb rod.
I think that it all comes together when you use the rod and reel together on the water. I have yet to get connected to a big GT and my casting abilities are flatteringly described as improving but some of the very experineced guys I go to for advice tell me its all good. In fact, one of them borrowed my rod last weekend when we were fishing to have a feel of it and launched a 150g popper a country mile. I'm sure that when it comes to fighting a fish the fact that the reel is overengineered is a good thing.
Hope this helps.

Trevor
