Not a lot.
Dont worry about it thats for sure, you will do it and think... is that it? assuming that you have a good amount of height.
OK so what will happen.....
You will 'park' the brakes, reach up to the trimmer tab adjusters and press them both at the same time, all that will happen at this stage is that you will need to wiggle a little bit to get them to fully open (until they wear in) The wing will gather speed and become more stable.
When you pull them in, you can do it in two stages to minimise sudden lift. 50% wait 1.2.3.4.5 then the other 50%
Once you are used to it you will hate being on slow trim I recon.
Good Luck but you dont need it.
