The Eyra tends to come out nose high anyway, so depending on what youre used too it may seem a little sluggish. A Bravo xs1 in 27, with two extra vent holes may work. I would try venting the prop you have first, as suggested by BCB. Also, I have found that loading my front compartments heavily greatly reduces the nose high take off. This may affect top end a bit but if youre running a 26p prop now youre probably not going for top end.
