I'll bite. First off Irvine Lake does a super job stocking the lake with feesh. Its a little pricey but worth the coin.
There is no one single "hot spot" for fishing ...you can find fish all over the lake!
I can't stand soaking bait so 99% of the fish I get are on the slow troll.
You do NOT need electronics for da vine.
Go for a paddle and enjoy the views of nature instead of your monitor. Keep it simple and you will enjoy your time on the water that much more.
As far as lures for Da Vine...I don't take much...but I almost always have out a Rapala cd-3 or cd-5 out in fire tiger flavor/color.
Also I use Panther Martins on the slow troll. (color is not important) These are are deadly along with Thomas Boyants.
*The most important detail IMHO is lure speed. Once you get this dialed you should be whacking fish. (1.2-1.6mph range works best for me)
I also use 6# mono line.
If yer into soaking bait...I have no advice.
One last thing...the bait shop has awesome breakfast burritos and the burgers are purdy tasty.
*BRING ENOUGH CERVEZA...beer is bucks up at the bait shop. ha
Good luck
I will probably fish the lake on Sunday.
