Which boiler for shower?

Sorry - I have had a previous thread similar to this, but am hoping for more advice...
I'm having fitted a Mira Atom mixer shower (big shower head + normal shower head size). Spoke to Mira who advise that they dont specify flow rates usually on their showers. However, they have sent me this flow chart ....related to flow rates. Mira did advise the shower cartridge will go up to 20 l/m at a push.

I'm going to fit a Valiant boiler, however central heating guy wont help me make my mind up to which boiler? Either the 28 (flow rate about 11/12) the 37??(flow rate about 15). I understand from Valiant that either boiler can be set to heat at the same gas running cost, but difference in heating water costs.
Just how important is it to get maximum flow rate? If I go for the bigger boiler, its gonna cost me £350 extra, but if I go for the cheaper boiler, will it be a decent shower??
Only live on my own, but adamant I want a decent shower. Will I actually notice any difference between the two boilers?
Sorry. I'm being a real pain with this....I would really appreciate some thoughts

I think you've answered your own question there. As you poined out, the 37kW boiler will give you a higher flow rate/better shower performance but at a cost.
However, a 'decent' shower is often a matter of opinion and only you can decide if its worth the extra money.
Personally, I'd be happy with the 28kW boiler but you might find it indequate which might explain why your Engineer was reluctant to advise you.You have been reading.....another magnificent post by garethgas :beer:0
