Help!!! joist selection

Hi all

I am undecide if to go for 90x45 or 120x45 joists (F7 H3 @ 600 centres). Cost is not an issue, height is slight concern, but the major concern is a bouncy deck!

According to the span tables I can space bearers at 1400 max using the 90x45 or 2100 using 120x45.

I would rather use 90x45, but would this still be bouncy if I use stick to the span tables? Or should I opt for the 120x45 to get a solid feeling deck?

Any advise or previous experince would be most appreciated.:2tsup:
