Personally I'd swap the 90 for the 110 - a lot lighter, as bright as you need and you don't need a centre filter.

However, then you'd had a spacing issue between 110 and 150 which would probably mean swapping the 150 for a 180..

I have the 110XL and have ended up with the following kits.

lightweight long hike kit

110XL, 200 Nikkor M, 300 Nikkor M

short hike kit

75 Rod Gran g/6.8, 110XL, 150 Sironar S, 240 Fuji A, 360/500 Nikkor T-ED

bells and whistles

58XL, 75 Rod Gran g/6.8, 110XL, 150 Sironar S, 200M, 240 Fuji A, 300 Nikkor M, 360/500 Nikkor T-ED


The 110 is such a nice lens that I woudln't ever want to get rid of it.
