Strategy for Lead-Up to Tournament

[Meltdwhiskey]

So I've been doing really well lately with my swing - so I thought.  My handicap has gone down almost 3 strokes in about 4 months.  And the swing has felt really good from a smooth / tempo standpoint - which had been a struggle to attain.

Also, I have an out of town tournament coming up at the end of the month in which I would really like to do well - AKA not embarrass myself.  Also, I've never really played in a tournament.  So I went and got a lesson at the local retailer to maybe just polish up a couple things.  However, all the guys that used to work there, don't anymore.

So the instruction I got is a pretty good deviation from what I've been doing.  Not just a polishing move here or there - but a little different concept.  And from the video - it seems to be very good advice.

I took it to the range this morn and was able to do OK - didn't blow my game up or anything.  But I'm unpracticed at it and have more tension and aggression now - and some army golf.  I'm sure I can smooth it out over time, but I only have a few times I'd be able to go hit balls.

So - anyone have an insight as to if it would be better to commit to the new / better / unpracticed ideas or hold onto the old stuff until I can get through the tourney?
