fruits require less concentrate than desserts custards. what percentage flavour are you using?
also you can soften fruits as well with a little something depending on the fruit type.
i would normally start around 5% with fruits and work up a bit.
though some fruits like pineapple which is very very strong and overpowering only need around 2%.
you can also try this ( one of my own recipes ) .. fruit with a fizzy tang )
water melon 9%
blueberry 7%
raspberry 4%
lemon lime 1.7%
EM 1.2%
koolada 2 %
menthol 6%
the above was a 12mg nic at a 50/50 pg/vg
lovely jubbly
also of note i always found Lorann to be very overpowering and rather unpleasant. i stick to Capella and TPA now.
I've tried using EM to see if that helps but he says it seems to mute the flavours. I think it's blueberry as everything I've made him has had blueberry in it even a blueberry cheesecake I've just mixed is still harsh for him.
I'll try reducing the % and see if that helps.
