I personally have not fished a lot of glo bugs. However, saying that, nothing beats Troutbeads from Troutbeads.com. Period. End of discussion. Nothing comes as close to matching the real eggs. They are deadly during the spawn and late Oct-December you will find me nymphing with one on my rig. Fished them last Saturday and nailed 16 fish, 12 on eggs. Plus, they are cheap. 40 count bags for around $3. Now you can also get mottled eggs that look like they are milking. Check them out at www.troutbeads.com
